Do you own a HW90 or Theoben pump?

Hi my HW90 is a little short of wind it’s putting out around 10.2 fp.

If you have a suitable pump I would be grateful if you could pump a little more life into my 90.

 

Regards in anticipation Pete

IF you can get the right connecting hose you can do it VERY carefully off a divers bottle like filling a pcp - its around the 50BAR mark - do not go over this - A - you wont be able to cock the rifle . B - the ram seals will 'burn' out VERY quickly

 

thats how ive done it in the past on theos and a '90k - borrowed the hose though

 

maybe someone like your local PIRTEK outlet could make a hose up if youve got access to a dives bottle an gauge

 

the dedicated theoben pumps and hose aint cheap if i recall correctly - just found em here - £22 for the hose / £75 all in

 

when i did it you pump it up, then tap the valve with a suitable tool - i used an allen key - to reduce the pressure to the right value - its just a heavy duty schraeder valve

Thanks for the reply Chris I don’t think I’ll risk the divers bottle method with my luck.
